Benefits of Address Validation

DOTS Address Validation - US 3 helps companies improve the efficiency of their mailings as well as improve customer satisfaction. This address validation tool runs in real time, allowing for instant verification at the point of entry into your system. The address verification API also corrects and appends address information. For example, if a customer accidentally transposes the numbers in the street address, the USPS® address check tool will recognize the address mismatch. Comparing the contact data with an extensive series of databases, our USPS® address verification service can quickly find the correct address for that contact and correct the entry. As a result, the USPS® address verification API allows you to reduce costs associated with lost, undeliverable, and returned mail.

At the same time, this address verification service ensures that customers receive their orders, correspondence, and special offers quickly without unnecessary delays. Companies use DOTS Address Validation to ensure that their marketing materials, sensitive correspondence, packages, and other mailings are promptly delivered with minimal delays due to incorrect or invalid addresses.

As a real-time address validation service, this USPS® address check tool allows for instant address verification at the point of entry. In addition, you can run address verification on demand to ensure that your mailing list is as accurate as possible despite changes of address.

DOTS USPS® address verification service quickly pays for itself by ensuring the deliverability of your entire mailing list. Each undeliverable mailer or package represents lost money and a missed opportunity. In addition, if a customer is anxiously awaiting a package that never arrives, trust can quickly erode. These problems can be avoided with our USPS® address validation API or by running an on-demand USPS® address check prior to mailing.

With access to real-time address validation web services and a regularly updated database of USPS® street addresses, you can ensure that mail arrives the first time. ... Read Less
